Photographs taken from directly above the Pacific Ocean have shown large areas of red light emitted against the backdrop of the surrounding environment, enough to rival the scale of a large city.

Ultraviolet-B (UV-B) semiconductor lasers are highly sought for medical, biotechnology, and precision manufacturing applications; however, previous UV-B laser diodes were limited to pulsed operation ...

Gaggione is highlighting adjustable beam optics for its Sirius range of LED optics. The zoom function is to allow switching between narrow and wide light distributions. For Sirius, there are two ...

Semiconductor nanowires, by definition, typically have cross-sectional dimensions that can be tuned from 2–200 nm, with lengths spanning from hundreds of nanometres to millimetres. These subwavelength ...

Abstract: We demonstrate highly efficient white quantum dot light emitting diode (QLED) devices using three separate quantum dots emission layers. The three luminescent layers are separated by two ...

Abstract: In this work, small-angle beveled-mesa termination technique was developed in GaN p-i-n power diodes for high avalanche performances. With effective alleviation of electric field crowding ...
